Yes, for sure Miss Collie..............700 or so hours on the WS tires. That is with rotating them perhaps every 3 or 400 or when I notice that the rears are really getting worn. I truly dislike changing those tires as the design of the hubs means you have to line up the holes and get them started rather than a bolt sticking out to hang them on and then put the bolts on them. Yes, I should just find the proper size bolt, cut the head off, thread it into the hole at 12 oclock and use it as a "stud" to hang the tire on and get the rest started.
Yes, I realize that grippers will give longer life, but for me, the place is pretty much hilly and when I have the aggressive tires on there are to many places around the barns, house, gates, heavy use areas, and just hilly pasture that I truly do NOT want to tear up with that heavy duty grab that those GOOD tires of yours do. It's bad enough that I have R4's on the B7610 tractor and they tend to rut or tear up sod quite a bit.
I use a LOT of mulch, ground up limbs from trees that I use for timber/firewood, around the place to build roads, paths, and fill in where the tires "dig in" a bit. Seldom do we get into a slippery place that just using the differential lock with the 4WD kicked in and we need more traction............Almost never.......lol.....I use the winch for pulling trees and stuff than I ever use for getting stuck. Except every now and then a neighbor will call that has gotten himself into a jam and needs help pulling himself or a visitor out of a ditch...............
BUT.......I truly see how you and Jamie can use HEAVY duty treads to get in and out off the "fun" on your daily travels and chores.............Well, back to the salt mines. My hired hand showed up which means I have to work.....SHUCKSOROONEY............God bless.......Dennis
